The
Royal Society report includes references to Clark et al, 2016 in Nature Climate Change, suggesting the final
sea level rise on millennia timescale caused by anthropogenic climate change (partly depending on future emissions) lies in a range between 29 to 55 metres and to DeConto & Pollard, 2016 in Nature, a study suggesting hydro - fracturing and ice
cliff collapse around Antarctic ice sheets increases high end projection for
sea level rise by 2100 to ± 2 metres.
